- 1). Add a small amount (2 to 3 oz.) of dental alginate into a cup.
- 2). Slowly pour in water and mix until the alginate powder becomes a thick paste.
- 3). Scoop the alginate into the upper dental tray, being careful not to overfill (you could make yourself gag).
- 4). Put the loaded tray over your upper teeth, holding it in place until the alginate hardens. Dental alginate sets in about 3 minutes, so you need to work quickly. When the alginate has become rubbery and solid, carefully remove it from your mouth.
- 5). Cover the alginate with a wet paper towel to keep it from drying out and repeat the process with your lower teeth.
- 6). Pour a small amount of water into a cup.
